BISOPE series 94- Pipe Fluid Vibration - Pipe Measurement Devices and Vibration-------------------------------------------------------------

There are measuring devices installed in pipes to determine the state of the flowing fluid (temperature, flow rate, flow velocity, etc.). These measuring devices are precision devices and are also vulnerable to vibration. In particular, there is a risk of being exposed to high pressure and may react particularly well to resonance due to location. Countermeasures are summarized through cases of gear/Roots flowmeters, thermometers, orifices, etc. that precisely measure accumulated flow.

BISOPE series 43- What does solid sound(Structure borne noise) mean?

--------------------------------------------------------------------------------------------------------------------------------------

The sound of bands and orchestras resounding in the concert hall entertains our brains. Unfortunately, we also analyze the sound. A string instrument that produces sound by plucking the string and its harmonics, a wind instrument that blows wind and produces a beautiful sound with the pipe's unique frequency, and a drum of its own size by beating a drum A percussion instrument that makes a percussive sound, and a keyboard instrument, a person's vocal cords vibrate, and a person's vocal cords vibrate in the throat... This is just music, but it is also called 'structure borne noise, air borne noise' in engineering. What does that mean? is it a guitar? is it a flute? is it a piano? Is it the sound of drums? Why are the pictures of railroad rails and wheels below?

 

The difference between 'structure borne noise, air borne noise'

 

1. What is the difference between the sound coming out of a speaker or mouth and 2. the sound made when hitting a xylophone or drum?
